# Theme

In this tab, you choose the theme of the application under development.

When creating the project, it is possible to choose a theme for the application. In this tab, you can change it to any of the available themes, such as *Achromatic*, *CornflowerBlue*, *Gray*, *GreenPine* or *MellowApricot*. Each theme shows a preview of the header, sub header, body, button and footer. Click the theme you want to apply it to the project. The selected theme is marked with a check.

The themes are shown in groups:

* **System** - The themes shipped with Kalipso.
* **User** - The themes you create. This group only appears, at the end of the list, after you create a theme.

If you don't want a theme in your project, choose **No Theme**.
